Polychlorinated biphenyl (PCB)-degrading bacteria associated with trees in a PCB-contaminated site

Article Abstract:

The abundance, identities, and degradation abilities of indigenous polychlorinated biphenyl (PCB)-degrading bacteria associated with five species of mature trees growing naturally in a contaminated site were investigated to identify plants that enhance the microbial PCB degradation potential in soil. The apparent association of certain plant species with increased abundance of indigenous PCB degraders including with organisms with outstanding degradation abilities, through the root zone supports the notion that biostimulation through rhizomediation is a promising strategy for enhancing PCB degradation.

Degradation of aroclor 1242 dechlorination of products in sediments by Burkholderia xenovarans LB400(ohb) and Rhodococcus sp. strain RHA1(fcb)

Article Abstract:

Burkholderia xenovarans strain LB400, which possesses the biphenyl pathway, was engineered to contain the oxygenolytic ortho dehalogenation operon, allowing it to grow on 2-chlorobenzoate and to completely mineralize 2-chlorobiphenyl. Inoculation at different cell densities did not affect the extent of polychlorinated biphenyl biodegradation.

Changes in bacterial populations and in biphenyl dioxygenase gene diversity in a polychlorinated biphenyl-polluted soil after introduction of willow trees for rhizoremediation

Article Abstract:

The positive and practical changes taking place in bacterial communities of a polychlorinated biphenyl (PCB)-contaminated soil after introducing host plant for rhizoremediation is studied. Results conclude that bacterial community was different from its parental community during the development of the Salix viminalis sp. root system.
